Creep is time-dependent deformation under load. Evaluate the relevant grade&#8217;s data at the intended stress and temperature, and define how much movement the assembly permits.<\/p>\n<p>PTFE illustrates why thermal capability and structural rigidity must remain separate questions. Carrara&#8217;s PTFE guidance discusses loss of sealing force through creep. A material may tolerate the environment chemically yet need a different support or sealing arrangement to maintain its function. A low coefficient of friction alone does not qualify it as a bearing material.<\/p>\n<h3>Moisture plus fit<\/h3>\n<p>For nylon, define the moisture state in which dimensions are accepted and the conditions the assembly will later experience. Ensinger&#8217;s machinable-plastics guidance notes that moisture uptake and release can alter dimensions. \u201cDry at inspection\u201d is therefore not equivalent to \u201cstable in a humid installation.\u201d<\/p>\n<p>Consider a hypothetical close-running roller. A small clearance established in a dry room may not represent the running clearance after environmental exposure. The design decision may involve a different grade, conditioning, revised clearance or another polymer\u2014not simply tighter machining.<\/p>\n<h3>Transparency plus impact plus cleaning<\/h3>\n<p>PMMA and PC should be compared using the finished optical requirement, not photographs of raw transparent stock. Curbell distinguishes acrylic&#8217;s optical appeal from polycarbonate&#8217;s toughness. Machining marks, polishing, thickness, scratches and the chosen stock grade affect the final viewing surface.<\/p>\n<p>Pour <a href=\"https:\/\/www.jccncmachining.com\/fr\/afficher\/lusinage-du-polycarbonate\/\">machined polycarbonate parts<\/a>, include the cleaning agents and fastening arrangement in the review. A clear part that looks acceptable before cleaning may not represent its condition after repeated use. Do not claim a protective or safety function from the polymer name alone; the complete design and applicable tests govern that use.<\/p>\n<h3>Sliding contact plus the mating surface<\/h3>\n<p>Friction and wear belong to a contact pair. Counterface material and finish, pressure, speed, lubrication, contaminants and temperature can change the result. Compare candidates in a representative contact test instead of selecting the smallest friction number from unrelated datasheets.<\/p>\n<\/section>\n<section id=\"grade\">\n<h2>Un nom de polym\u00e8re n'est pas une d\u00e9signation compl\u00e8te de mat\u00e9riau<\/h2>\n<p><img decoding=\"async\" width=\"1024\" height=\"576\" loading=\"lazy\" src=\"https:\/\/www.jccncmachining.com\/wp-content\/uploads\/2026\/09\/polymer-stock-grade-distinction-1024x576.webp\" alt=\"Unfilled and reinforced polymer stock\" class=\"size-large wp-image-2245 aligncenter\" \/>\nState the manufacturer or approved equivalent, product grade, filler content, colour where relevant, and required stock form.
